convert xml to html list with xslt - xslt

Question

I have a xslt code to convert an xml file to html list. The input and output samples are as follows:
Input:
<Beverages>
<Water/>
<Coffee/>
<Tea>
<BlackTea/>
<WhiteTea id="cti" value="ctv" >Camomile Tea</WhiteTea>
<GreenTea id="gti" value="gtv">
<Sencha/>
<Gyokuro/>
<Matcha/>
<PiLoChun/>
</GreenTea>
</Tea>
</Beverages>
and the Output:
<ul>
<li>
<span class="caret"><Beverages></span>
<ul class="nested">
<li><span><Water/></span></li>
<li><span><Coffee/></span></li>
<li>
<span class="caret"><Tea></span>
<ul class="nested">
<li><span><BlackTea/></span></li>
<li><span><WhiteTea id="cti" value="ctv"></span>Camomile Tea<span></WhiteTea></span></li>
<li>
<span><GreenTea id="gti" value="gtv"></span>
<ul class="nested">
<li><span><Sencha/></span></li>
<li><span><Gyokuro/></span></li>
<li><span><Matcha/></span></li>
<li><span><PiLoChun/></span></li>
</ul>
<span></GreenTea></span>
</li>
</ul>
</li>
</ul>
<span></Beverages></span>
</li>
</ul>
Here is my xslt but it is not exactly the same as what I want:
<xsl:template match="/">
<ul><xsl:apply-templates/></ul>
</xsl:template>
<xsl:template match="*">
<li> <span class="caret"><xsl:value-of select="concat('<',name())" />
<xsl:for-each select="#*">
<xsl:value-of select="concat(' ',name())"/>=<xsl:value-of select="concat('"',.,'"')" />
</xsl:for-each>></span>
<xsl:if test="text()">
<xsl:apply-templates select="text()" />
</xsl:if>
<xsl:if test="*">
<ul class="nested"><xsl:apply-templates/></ul>
</xsl:if>
<span><xsl:value-of select="concat('<','/' ,name() , '>')" /></span></li>
</xsl:template>
The problem is that this code can not differentiate between parent elements and non parent element. for parent elements we need to add class="caret" attribute, but for non parent elements we shouldn't add this class.

This should work for you.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<ul>
<xsl:apply-templates/>
</ul>
</xsl:template>
<xsl:template match="*">
<li>
<span>
<xsl:if test="*">
<xsl:attribute name="class">
<xsl:value-of select="'caret'"/>
</xsl:attribute>
</xsl:if>
<xsl:value-of select="concat('<',name())"/>
<xsl:for-each select="#*">
<xsl:value-of select="concat(' ', name(), '=', '"', ., '"')"/>
</xsl:for-each>
<xsl:choose>
<xsl:when test="text() or *">
<xsl:value-of select="'>'"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="'\>'"/>
</xsl:otherwise>
</xsl:choose>
</span>
<xsl:if test="text()">
<xsl:value-of select="text()"/>
</xsl:if>
<xsl:if test="*">
<ul class="nested">
<xsl:apply-templates/>
</ul>
</xsl:if>
<xsl:if test="text() or *">
<span>
<xsl:value-of select="concat('<','/' ,name() , '>')"/>
</span>
</xsl:if>
</li>
</xsl:template>
</xsl:stylesheet>
